Given that Stuttgart only built twenty-five, the answer is "never." Canepa Design has this one sitting on its showroom floor in Scotts Valley, California, just outside of San Francisco. Shouldn't every afternoon have a little German ubercar in it?

The surprise here isn't so much that this car is for sale — if there's anyone in the U.S. who would be selling a 959S, it's Bruce Canepa, the man/company/917-driving wunderdude who helped make the '59 street-legal in America — but that it's for sale on Craigslist. Business a bit slow these days, Bruce?
